The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Nephroma tangeriense - a lichen

Range & Status

Described as new to the British lichen flora from moss-covered, exposed, south-facing serpentine rocks on the Lizard Peninsula. It has since been found elsewhere in West Cornwall, on the Isles of Scilly (Tresco) and the Lleyn Peninsula in North Wales. Elsewhere it is known from the western Mediterranean and from Macronesia. Never very abundant, it is threatened by the encroachment of Ivy Hedera helix , Bramble Rubus fruticosus agg., Bracken Pteridium aquilinum and Blackthorn Prunus spinosa at its two Lizard sites, both of which lie within SSSI.
